Surefire X300U-B

Everyone is at the least familiar with the Surefire X300 weapon light.  It’s been around a long while now  for something gun related.  Recently they have come up with a upgrade on the old X300 with the 300U-A  and B.


The A uses the old system and the B has the new T-slot  with bolt to tighten with.

A much much better method  if you are putting it on a 1913 rail.

Below is the older system  and new compare.

Just be sure not to get over enthusiastic if you are tightening the new system on a polymer framed handgun.

One of the other very recent upgrades is boosting the light  to 1000 lumen.
